>Well, see, if human population plunges enough, then there wont be the society that favors low fertility. In that scenario, no one does well. Back when we lived primitively, there was a large young population, tens of millions globally. Any single death or small group of deaths didn't really threaten extinction except locally (usually not even that). But though total population will be high even well into this era, it will be top-heavy with geriatric humans. A few deaths of those of reproductive age could have grim consequences. Everything works counterintuitively with declining populations.
